Explanation
- Robot Class:
- Attributes:
x,y: Coordinates of the robot on a 2D grid.
- Methods:
move(char direction): Updates the robot’s position based on the direction command.- ‘U’: Moves the robot up by incrementing the y-coordinate.
- ‘D’: Moves the robot down by decrementing the y-coordinate.
- ‘L’: Moves the robot left by decrementing the x-coordinate.
- ‘R’: Moves the robot right by incrementing the x-coordinate.
printPosition(): Displays the current position of the robot.
- Attributes:
- Main Function:
- Robot Creation: Initializes a
Robotobject at the origin (0, 0). - Control Loop:
- Continuously prompts the user for a command to control the robot.
- Commands:
- ‘U’: Move up.
- ‘D’: Move down.
- ‘L’: Move left.
- ‘R’: Move right.
- ‘Q’: Quit the simulation.
- Position Update: Calls
movemethod to update the robot’s position based on the command. - Simulation End: Prints the final position of the robot when the user quits.
- Robot Creation: Initializes a
Usage
- Robot Motion Simulation: Provides a basic simulation of robot movement on a grid using directional commands.
- Control Mechanism: Demonstrates simple user input handling to control the robot’s movement.
